Serial Port Connector 10-1 Pin Com1

where are you quoting this from???

I would not expect to.

It used to connect devices such as a modem, mouse etc. not a printer as has been suggested,This would have been a Parallel port. These connection were superseded by usb etc.

It's an old port that was used for printers and similar devices years ago.

Do you need it? No.

A useless port for this day and age here's a guide video to learn about it

It is used for old printers and these days we use usb for all of that so you can even go into bios and disable it as it does nothing.

I never use them now cuz now we have USB so common anyway this is what it looks like http://h30434.www3.hp.com/t5/image/serverpage/imag...
